I'm using targetPageParams to add a parameter into the mbox (default mbox), lets call it "MyParam".
In my script its pulling in a querystring parameter and setting a custom mbox parameter to the value found there.
Example URL: [my URL]?TESTParam=xyz123
I know Target has seen "MyParam" in the mbox because it offers that parameter ("MyParam") as way to build audiences off of, in "Custom" rules.
That being said..if I wanted to create an experience that now uses the value found in MyParam on the page, let's say appending it to a text field. How can I do that? I tried using ${mbox.MyParam} in a SetHTML modification for a text area in the content section. This did not appear to render anything.
What am I missing? Is the syntax ${mbox.MyParam} for adding that mbox variable to the page correct? Is there another way to do it?
Thanks for any help.
